DIY T-Shirt Mask

I came across instructions for a DIY T-Shirt Mask that was developed by researchers at the University of Pennsylvania, tested at Los Alamos National Laboratories, and shared by the CDC. All that’s needed is a t-shirt, marker, scissors, and ruler.

I made DIY T-Shirt Mask to share with homeless shelters and houseless people as well as folks in marginalized communities. I also have jpegs (below) in English/inches and Spanish/centimeters and the Plain Text for T-Shirt Mask, in case you want to make a prettier flyer or do one in Spanish.

Print some flyers and hand out when you venture outside your home. Or make some masks and hand those out.

Instructions for Simple Respiratory Mask


These instructions were based on guidelines shared by the Center for Disease Control. These guidelines are for “making an effective face mask if surgical masks and N95 masks are unavailable during a viral outbreak.” The original design was created by researchers from the University of Pennsylvania who tested with employees at Los Alamos National Laboratories.

Read the original instructions and research.

This mask can provide a good fit and a measurable level of protection. Testers wore the prototype mask for an hour without difficulty. Breathing through this mask is subjectively no different than breathing through an N95 mask, but persons with respiratory compromise of any type should not use this mask.


  • 1 Heavyweight T-Shirt
  • Scissors
  • Marker
  • Ruler
  • 1 Microfiber cloth (optional


It’s preferred that the T-Shirt is first boiled for 10 minutes and air-dried. This will maximize shrinkage and sterilize the fabric.

  1. Cut piece about 28 inches X 15 inches and lay out horizontally.
  1. Mark your 4 cut lines, all 8 inches long.

  1. Mark placement of square layers: in center, about 2 inches from the bottom.
  1. Cut along the four 8 inch lines described in #2. Do NOT cut center square
  1. Using remaining T-Shirt to cut 8 more pieces that are about 8 inches square.

Sizes can vary slightly. Try to make 4 squares by cutting with the grain of fabric (straight grain) and 4 squares by cutting across the grain of fabric (cross grain).

Optional: Cut an 8 inch square out of Microfiber and place in first layers.

  1. Stack squares on top of larger piece, in marked area.

Layers 1 & 2: straight grain, horizontal
Layers 3 & 4: cross grain
Layers 5 & 6: straight grain, vertical

  1. The top is rolled down to make Tie A, including part of the layered pieces.
  1. In center of rolled Tie A, cut a small vertical slit (through 1 or 2 layers of fabric) so it will fit snugly over bridge of nose.

  1. Adjust around nose to eliminate leakage. You can add extra fabric under the roll between cheeks & nose and/or push rolled fabric along bridge of nose.
  1. The center of Tie B is placed under chin. The bands go up, in front of ears, & and are tied at the top of the head. Add extra cloth to bands, as needed.
  1. Tie C is tied at the back of the head. The bands can go above or below ears, whichever provides a more complete seal.

Black History Month, Boss Bitches, and Eartha Kitt

Last year during Black History Month I tried to do a post every day about an innovative black American whose name was likely not currently common knowledge, starting with Carter G. Woodson, the historian who started Black History Month, and ending with Octavia Butler, a science fiction writer. And, I tried to not focus on the “predictable” focus areas of black excellence, such as athletics and music. I wanted to hi-light how time and time again black Americans fought adversity, excelled, and changed our world, such as with Percy Julian, who was instrumental in creating birth control, or Bayard Rustin, the civil rights and gay rights activist who brought the non-violent teachings of Ghandi to MLK Jr. Continue reading

Octavia Butler

On this last day of Black History Month, let’s carry forward the legacy of black Americans who, despite their struggles in this violently oppressive country, have shown innovation, talent, depth, and courage. And, let’s look to what is possible in the future.

I was a fan of science fiction and fantasy fiction as a child. It was my favorite escape – imagining impossible adventures, fantastical creatures, emotion-driven characters, good and evil, mystery and magic, creativity and curiosity, exploration and adventure, legacy and the future. The majority of these stories, though, are obviously rooted in western, white patriarchal concepts. I distinctly remember my excitement when I first read Madeleine L’Engle’s A Wrinkle In Time – how refreshing to read about a young, female protagonist! Then, as an adult, I found Octavia Butler, a black woman science fiction writer – an afrofuturist who’s short bibliography shifted the white male-dominated field of science fiction with amazingly crafted worlds and powerfully disturbing stories of struggle, colonization and oppression, perseverance, hope, and change.

Ralph Bunche

As Black History Month nears its close, I have come across another innovative, radical, groundbreaking, extremely intelligent individual who few likely know by name. Ralph Bunche was an academic, political scientist, activist, and diplomat. While alive, he was celebrated for his peacekeeping efforts in the Middle East, Africa and the Mediterranean, for helping form the United Nations, and for his work in the Civil Rights Movement. And, not only was he the first African American to be awarded the Nobel Peace Prize, he was the first person of color to receive the award.

Mae Jemison

This post goes out to my 7-year old science-loving niece, Xenia. I hope that learning about all of these innovative and brilliant black Americans will inspire you to shoot for the stars.

You’ve probably seen a particular photo of Mae Jemison before: an orange puffy suit,  a black round helmet, and a beautiful smile. But, like so many other groundbreaking black Americans, you probably don’t know her by name. Jemison is an engineer, physician, and astronaut. In fact, she was the first African American woman in space.

Florence Griffith Joyner

There are three reasons I want to do a Black History Month post about Florence Griffith Joyner: I purposefully stayed away from featuring athletes, because sometimes it seems like that’s the area most people focus on when considering the accomplishments of black Americans (and the approach starts to feel a little too reminiscent of seeing black Americans as property and not people), but there is no denying that there are many amazing black athletes who deserve to be recognized; Flo Jo is one of the athletes I recall most from my youth; This photo is everything.
